Foreword
4.2.1, 4.2.2 a), 4.2.3.2, 4.2.4, 4.2.5.1, 4.2.6, 4.2.7.1, 4.2.8, 4.2.9 and 4.3 in this standard are
mandatory and the others are recommendatory.
This standard is adopted from IEC 60839-10-1:1995 Alarm systems – Part 10: Alarm systems for
road vehicles – Section 1: Passenger cars (English version).
This standard is redrafted according to IEC 60839-10-1:1995. For comparison, the informative
Annex A gives cross references of the clauses between this national standard and the international
standard.
Allowing for the state of the nation and the development requirements of vehicle security protection
and making reference to the relevant international regulation and standard, i.e. Annex VI: Scope,
definitions and requirements for vehicle alarm systems of COMMISSION DIRECTIVE 95/56/EC
of 1995 and British standard of insurance industry Security system evaluation – Passenger cars
(1996 Edition 2), this standard adopts and partially modifies IEC 60839-10-1:1995. These technical
differences have been marked with perpendicular single lines at the margin of relevant clauses. The
summary list for these technical differences and their reasons is given in Annex B for reference.
This standard modifies IEC 60839-10-1:1995 mainly in three aspects: prevention against false
alarms and noise disturbance, improvement of protection level, easy understanding and use, as
detailed below:
-- As prevention against noise disturbance from the warning device of vehicle is a great national
and public concern, this standard cancels the requirements of IEC60839-10-1:1995 regarding
sending out non-warning audible signals by sound signaling device, allows reduction in alarming
sound level, limits the repeated warnings, and adds test on prevention against false alarms
(Annex D);
-- Allowing for the current means of vehicle burglary, the anti-theft alarming is to be of higher
requirement, so methods and higher requirements for unsetting, warning and immobilization of
VSAS are added;
-- To adapt to the development of anti-theft alarming technology for vehicles, contents regarding
protection with VSAS and networking are proposed;
-- To evaluate VSAS more accurately and support risk rating for vehicle insurance, protection
classification of product by protection performance is added;
-- Basing on the original IEC 60839-10-1:1995 and referring to relevant international standards,
some contents are detailed and some correlated contents are arranged collectively.
Vehicle Security Alarm Systems - Passenger Cars
1 Scope
This standard specifies technical requirements and test methods for vehicle security alarm systems
(VSAS) intended for installation within vehicles used for the carriage of passengers and having not
more than eight seats in addition to the driver’s seat, i.e. M1 category.
The object of the standard is to ensure a high standard of safety, performance and reliability of the
VSAS and the reduction of false alarms.
The standard covers VSAS designed to detect and signal the unauthorized opening of any of the
vehicle doors, boot/luggage compartment, bonnet/engine hood and, in addition, to immobilize the
vehicle when set.
The standard covers VSAS intended both for installation as original equipment and or installation
after delivery of the vehicle.

An electrical/electronic device, e.g. remote control and inductive type switch, shall either
Case I -- have a coded transmitter signal with at least 50000 effective combinations and have
a minimum scan time of 24h per 5000 variants; or
Case II -- incorporate automatically changing codes, e.g. rolling codes, jumping codes, such
that the mathematical chance of obtaining the correct code within 24 h is less than 4 %; or
Case III -- incorporate codes at least meeting the requirements of Case II and also a
transmission mode not imperceptible (e.g. optical transmission of narrow angle).
d) If this is a coded key incorporating directly electrical connection:
It shall incorporate codes at least meeting the requirements of the Case II as specified in the above
c) and such that the mathematical chance of obtaining the correct code within 24h is less than 4%.
If this coded key switch is fitted within the vehicle, the entry period shall be timed, see f);
e) If this is a biometric key:
Since the biometric characteristics of human body constitute the key to identify each authorized
person, the maximum keys accommodated/stored, nmax, shall be provided so that at least five
unauthorized person(s), who operate at the fastest identification rates, cannot be identified as
authorized person within 5 min or that the chance of identifying an unauthorized person as
authorized within 24h is less than 4% of the nmax.
If this identification device is fitted within the vehicle, the entry operation period shall be timed,
see f).
f) If the key switch/device for code entry is fitted within the protected passenger compartment
If this key switch/device is fitted within the vehicle in conjunction with a timed entry period,
the time allowed to unset the VSAS after the opening of the door, shall be not less than 5 s and
not more than 15 s.
4.2.5 Warning signal
The alarm condition shall be indicated by an acoustic warning signal, or may be indicated in addition
by (an) optical warning signal(s) or remote wire-free signaling or any combination of these.
The warning signal shall be activated once for every detection. However, within one setting period,
at most 10 repeated activations of acoustic warning signal are allowed to each detector (so as to
avoid endless warning).
